It is a piece of Lexmark software within the driver subsystem. It can cause issues with consuming too many handles and crashing subsystems

This program causes my CAD to not operate. I remove this one file from the Processes and it will work. I am using Tango PCB, removing it does not stop the lexmark printer from working.

Best practices for resolving lmabcoms issues

A clean and tidy computer is the key requirement for avoiding problems with lmabcoms. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command.
